HINGE. I

Specification of Letters Patent. {Patented NOV. 11, 1913. App1icationfiled September :18, 1911. Serial no. 649,973.

To all whom it may concern Be it known that I, FREDERICK SoHnnY, a

citizen of the United States, residing at New Rochelle, in the county ofWestchester and State of New York, have invented certain new and usefulImprovements in Hinges, of which the following is a specification.

My invention relates to improvements in hinges of the style that havemeans permitting of setting or positioning the two leaves at differentangular positions relatively one to the other and locking means tendingto hold the said leaves at the positions to which they are set, and theobjects of my improvements are to provide spring holding means, andmeans for adjusting the tension of the spring and to provide such meansas are convenient and efficient in OPQI'? ation.

In the accompanying drawing :Figure 1 is a side elevation of my improvedhinge. Fig. 2 is a rear elevation of the same. Fig. 3 is a plan view ofthe same. Fig. 45 is a plan view of the left leaf member. Fig. 5 is aplan view of the right leaf member. Fig. 6 is a sectional view on theline was of Fig. 3, in part broken away, and on an enlarged scale. Fig.7 is a side elevation of one of the adjusting members. Fig. 8 is a planview of the same. Figs. 9 and 10 are views similar to Figs. 7 and 8, oftheother adjusting member. Fig. 11 is a plan view of the movable lockingmember. Fig. 12 is a bottom view of the same. Figs. 13 and let are viewssimilar to Figs. 11 and 12, of the fixedlocking member.

A is my hinge and comprises aleft member B and a right member C,connected to gether by a joint comprising a combination of a pivotalconnection and an adjustable stop device to be described. The leftmember B comprises a hinge leaf 20, comprising a plate like memberhaving holes 21 for supporting screws and along the inner edge has ateach end a knuckle 22, the two constituting a pair of end knuckles,separated by a space 23. The end knuckles 22 are provided with holes 24that are square sided and in axial alinement and which holes are afitfor the square body of an axial bar or shaft D. The right wing Ccomprises a hinge leaf 20 and integral with one end thereof anintermediate knuckle 25, suitable for being received in the said space23 between the end knuckles 22 and provide space between the upper end26 and the upper end knuckle 22 forthe head 27 of an adjusting member Eand also if desired, to provide space between the lower end 28 andthelower end knuckle 22 for a fiber washer F, which serves as a bearingmember. The intermediate knuckle 25 is bored longitudinally to provide achamber G suitable for housing mechanism to be described. y

In the lower end of the chamber G there arepositioned a pair of lockingmembers having engaging jaws comprising a lower locking member II and anupper locking .member I. The lower locking member H fills thellower endo-fthe said chamber G and is secured in position by a radial pin J, hasan. axial hole 29 than is circular of size such as to permit the squareshaftD to turn therein and is provided on the :upper face with aset ofradial teeth 30. The upper locking member I .is essentially the same asthe fixed locking member .I-I reversed, except that itis provided with asquare axial hole'31; that is an operative fit for the axial shaft D,and the outer wall is a fit for the cylindrical wall of the said chamberG,

whereby the upper locking member I is free to turn and .movelongitudinally in the.

chamber G, guided axially by the axial shaft D. Thesaid jaws or teeth 30are so shaped that when held in resilient engagement under normalconditions in a manner to be described, 1 they will prevent relativeturning of the. leaf members B and C. under normal or moderateconditions tending to effect such movement, butvunder abnormalconditions and a "strong tendency to produce a relative turningmovement, the said jaws or teeth will slide relatively one to another,raising the upperjaw member I, and will permit such movement, the jaws30 again engaging after the desired change in position has beeneifected. V

The upper face 32 of the upper locking member I is an annular planesurface, suitable for a bearing for the. end of the spring Thesaidspring K is a coil spring, surrounding the axial shaft D, andoccupies the greater part of the chamber G, the lower end resting on.the annular bearing surface 32 of the upper locking member I and theupper end is similarly engaged with the lower end 43 of the slidingmember L of an adjusting device to be described. The said adjustingdevice comprises the sliding membe'r'L and the turning member E that areengaged by their cylindrical and sleeve-like with, and the body portion35 of the sliding member -L being provided with a square '7 ,niular informationandfi lls the space beposed between'the lower end knuckle 22 onv member I,.:turns the sanienvit-h the shaft '1 jand any tendency toturn the ring members the spring K by the adjusting device.

A hinge comprising .apair of leaves connectedtogether by a joint comprising a pair of jawsheld in engagement by a spring, means of adjustment of the said springcomprising a pair of adjusting members respectively an inner member andan outer member engaged one'w'ith the other by a screw thread, the outerof the said adjusting members accessible and having means for beingturned for purpose of adjustment, and the inner of the said adjustingmembers provided with -means for preventing rotative motion thereof andpermitting of movement axially in response to a turningmovement of thesaid outer adjusting member comprising a square shaft engaged with anaxial hole in the said inner adjusting member.

2. A hinge comprising a leaf having a pair of end knuckles provided withsquare holes in axial alinement and a square shaft rigidly securedtherein, and a second leaf provided with an intermediate knucklehaving:an axial chamber surrounding the said shaft, and separated at one endfrom one of the said end knucklesby an annular adjustinghead, a pair oflocking members having coacti n-g jaws at the other end of the saidchamber, one beingjfined to the said intermediate knuckle and free toturn on the said shaft, and the other free to turn in the said chamberand a fit for and free to slide along the said shaft, a slidingadjusting member having a hole fitting and surrounding the said shaft,and provided with screw vthread engagement with the said adjusting head,and a spring surrounding the said shaft and engaged by its ends with thesaid otheralockingmeniber on one end and the said sliding adjustingmember on the other end.
